contentTopSpacing (18pt) was stacked on top of the content VStack's
own 24pt inter-section spacing, giving header-to-Categorias a wider
gap (42pt) than every other section-to-section gap in Home (24pt).
Dropping it to 0 makes the gap consistent with the rest of the
screen.
Resolves the App Attest env/entitlements changes onto the flattened
PediFoods.xcodeproj structure (Darwin/PediFoods.xcodeproj no longer
exists on this branch). Also restores Release signing to Manual /
Apple Distribution / AppStore provisioning profile - the merged-in
fix had switched it to Automatic / Apple Development, which breaks
headless CI archiving.
